REINFORCED. CONCRETE CONSTRUCTION.

structures of this oharact'er,whereby the latter will uniformly'resist the various forces tending to strain, break, or otherwise injure the same.

A further object of the invention is to improve such constructions by the employment of a reinforcing core or chain formed of a plurality of independent links adapted to be embedded in the concrete, cement, or other material forming the culvert as the latter is being built.

A still further object is to form the several reinforcing-links with terminal hooks adapted to engage the laterally-extending loops of adjacent links, said links being-preferably formed of twisted-wire cable to thereby offer an extended roughened surface to the bind ing action of the cement or concrete.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto ap ended, it being understood that various cfianges in form, proportion, and minor details of construction may be resorted to without departing from 1 the principle or sacrificing any of the advanages of this invention.

In the accompanying drawings, forming apart-of this specification, Figure 1 is a longitudinal sectional view of a culvert constructed in accordance with my invention. Fig. 2 is a transverse section taken on the line 2 2 of Fig. 1. Fig. 3 is a detail perspective view of one of the reinforcing-links detached. Fig. 4 is a similar view showing two of said links interengaged or coupled. Fig. 5 is a sectional plan view of the bottom of the culvert, illustrating a modified form of reinforcing-link.

Similar numerals of reference indicate cor responding parts in all the figures of the drawings.

In the preferred construction 5 represents a culvert constructed of concrete, cement, or other suitable material, said culvert, being Specification of Letters Patent;

provided with oppositely --disposed vertical guard-walls 6, defining a driveway 7 and having an arched waterway 8 arranged at right angles to the driveway 7, as shown. Extending transversely across the bottom 9 of the culvert and molded or otherwise embedded in the concrete of which the latter is formed are a plurality of reinforcingcha ns, preferably laid side by side, as shown in F gs. 2 and 5 of the drawings. The reinforcingchains are composed of a series of independent links 10, preferably formed of twistedwire cable, so as to present an'extended .roughened surface to the binding action of.

the concrete and cause said links to be firmly embedded therein. The links 10 may be made in different sizes,\.a'ccording to the nature of the structure to be reinforced, and each preferably comprising a pair of parallel arms 11, .connected at one end by a transverse bar defining a laterally-extending loop 12, and having their 0 posite ends bent upwardly and rearwardly to form terminal hooks 13, adapted to slidably engage the connecting-bars of adjacent links when'properly positioned in the cement to form the reinforcing-chain. The links 10 are separate or disconnected, as before stated, and preferably embedded in the cement or concrete while the latter is still in a plastic condition, as many of said links being joined together and arranged side by side as may be found necessary to properly reinforce the culvert or other structure. Embedded in the guard-walls 6 of the culvert are a series of spaced vertically-disposed links 10, similar .to the links 10, but of varying length, as

shown, while embracing the parallel arms 11- of said vertical links are a plurality of diagonally-disposed links 14, the terminal hooks 15 of which are preferably disposed adjacent to the arched wall of the driveway 7.

having the links embedded in the vertical walls of the culvert in the manner stated said walls are materially reinforced and effectually prevent-ed from crackin when subjected to severe strains, while the links 10, extending transversely across the base of the structure, tend to brace and bind said walls and prevent settling of the arch. Embedded in the concrete or cement forming the driveway 7 are a plurality of similar reinforcing-chains 15, preferably extending between the vertical guard-walls 6 and following the general curve of the arch of the waterway, as shown.

The links forming the chains 15 are similar in construction to the links shown in Fig. 3, but are so laid or embedded in the concrete as to form a truss and give additional strength to the culvert where subjected to the most strains. a

In Fig. 5 there is illustrated a slightly-dif ferent form of reinforcing chain, in which the spaced bars 16 of the individual links converge toward the terminal hooks instead of being dis osed parallel, and these links, although s own in actual engagement with each other, may be spaced a short distance apart, if desired, without departing from the spirit of the invention.

The links while preferably formed of wire cable may be formed of iron bars s uare or angular in cross-section and twisted into the desiredshape, the result accomplished being I the same in both casesnamely, to present a roughened surface to thecement or other plastic material. I

A culvert constructed in the manner described will effectually prevent cracking or disintegration of the cement or concrete generally due to climatic changes and effectually withstand all strains incident to the passage of heavy wagons or other vehicles over the driveway.

Having thus described the invention, what is claimed is- 1. A concrete construction having a plurality of reinforcing-cores embedded therein, said cores being formed of a series of se arable links each provided at one end wit a transverse bar and having their 0 posite ends provided with terminal hooks the bills ofwhich are open and slidably engage the transverse bar of an adjacent link.-

2. Aconcrete construction having a lural-' ity of reinforcing cores embedded t erein, said cores being formed of a series of separable-links each comprising apair of s aced arms, the ends of which arebent lateral y beyond the general plane of the links and connected by an unobstructed transverse bar, said arms terminatingin rearwardl -disposed books the bills of which are space from said arms and slidably engage the connectingbars of adjacent links.

. In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
